摘　　要：在规划出安全走廊和参考航迹的情况下,利用非线性规划法,提出了一种新的低空突防最优航迹算法。该算法考虑了飞行器机动能力约束,使最优航迹不需要平滑处理就是一个可实现航迹,同时也考虑了地形及威胁对最优航迹的影响。另外,打破了将威胁当作一座山的传统处理方式,使最优航迹不仅能紧密跟踪地形,而且能自动有效地回避威胁。更重要的是采用分段规划思想,使优化速度大大提高。计算结果表明,该算法畿产生平滑的三维突防航迹,并具有实时性。A new algorithm to obtain optimal flight-path of vehicle penetrating at low-altitude is presented by using nonlinear when the safe-corridor and referent flight-path is determined. The algorithm takes account of flight maneuvering constraints, usable flight-path is obtained without the need for any additional smoothing to assure that all constraints are met. Also the effect of terrain and threat is consider, thus, the optimal flight-path generated can not only closely follow the terrain but also automatically evade threat. It is important that the calculating speed is high by calculating a part of the whole flight-path each time. The simulation results are provided to show that the optimum three-dimensional generated is smooth and the algorithm can be used in real-time.
